Abstract
The utility model discloses an automatic water pump without electric power consumption, and the automatic water pump uses the magnetic force of a permanent magnet. The utility model is provided with a movable contact point 4 and a static contact point 5 of a switching circuit; a float 7 and a top rod 6 are combined with an iron piece 3, and the iron piece 3 is matched with a nearby permanent magnet 2; the iron piece 3 passes through a connecting ring line 8 to be connected with a connecting ring float 9 together through the top rod 6 and the float. The buoyancy of the water which arrives at the rated water line is used to enable the iron piece and the permanent magnet to generate the attract kinetic energy. When the water level is in the lowest water level, the utility model uses the gravity generated from the condition that the connecting ring float disengages from the water to generate the disengaging potential energy for automatic water pumping. The utility model is suitable for water pumps of water towers and various cisterns.
Description
The utility model relates to the automatic water pump of a kind of water pumper starter, especially control circuit under water level.
At present: water tower, and the water pumper of various reservoirs all needs the special messenger to draw water basically, for solving this difficult problem, utilize the kinetic potential of water level buoyancy, make automatic water plug in water level: its structure is movable contact, the stationary contact of switching circuit, float and push rod drive contact work under water level, but, minor variations when water level rises or descends, the capital makes contact energising or outage, causes the water pumper Fraquent start, is difficult to avoid electric arc to burn out the contact, its practical value is little, can only rest on principle demonstration and the education experiment.
In the People's Telecon Publishing House: " the little making collection of choice specimens of practical electronics " the 132nd page of " electronics automatic water pump " literary composition that publish in February, 1991 discloses by water level detection circuit, control circuit is formed with executive circuit and power circuit, its deficiency is: technology is complicated, accuracy requires high, and the component cost reaches consumed power greatly.
The purpose of this utility model provides a kind of simple and practical, and consumed power not utilizes the automatic water plug of permanent magnet magnetic force.
Realize the purpose of this utility model be float and push rod in existing automatic water plug make up have iron plate and near permanent magnet match, this iron plate, links together with a chain of float by way of a chain of line through push rod and float.When water level rises to specified waterline, iron plate by near permanent magnet magnetic force institute adhesive, produces adhesive kinetic energy under water buoyancy, make movable contact switching circuit.
Under the water level that descends, float slowly breaks away from the water surface, because of himself gravity lighter, attract the magnetic force of iron plate less than permanent magnet, still attracted by the magnetic force of permanent magnet and iron plate, reach lowest water level along with the water level that descends falls, drawn a chain of float by the float of permanent magnet and iron plate magnetic attraction by way of a chain of line and also break away from the water surface, so the gravity stack, during greater than the magnetic force of permanent magnet and iron plate, make the rapid and permanent magnet disengaging of iron plate, produce disengaging potential energy, make movable contact be circulated in closure repeatedly, the process of disconnecting circuit, thereby opening of control water pumper, stop, realize that nobody draws water automatically, be applicable to water tower, and on the water pumper of various reservoirs.
Because in the above-mentioned solution, by the water buoyancy that arrives specified waterline, make iron plate and permanent magnet produce adhesive kinetic energy, reach water level and fall when reaching lowest water level, break away from the gravity of the water surface by a chain of float, produce and break away from potential energy, finish function closed and disconnecting circuit, so structure is simple especially, but quite practical, consumed power not.
Below, in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Fig. 1 is the structural representation according to the utility model embodiment.
Fig. 2 is according to the utility model auxiliary work schematic diagram of connecting with the QC magnetic starter.In principle assumption diagram shown in Figure 1 in automatic water pump housing 1, movable contact 4 and stationary contact 5 that the switching circuit is arranged, float 7 makes up iron plate 3 to be arranged and nigh permanent magnet 2 is set with the top of push rod 6 and matches, and this iron plate 3 links together with a chain of float 9 by way of a chain of line 8 through the bottom of push rod 6 and float.
As shown in Figure 2, automatic water pump is installed in the waterline of water tower, extracting power supply cord and QC magnetic starter control circuit are in series in the tower, after connecting power supply, the starter electromagnetic mechanism drives main circuit contact, water pumper draws water automatically, the pump-out of water tower rises immediately, along with the water level 10 that rises arrives specified waterline, under water buoyancy straight up, make the iron plate 3 of float 7 and push rod 6, under near permanent magnet 2 magnetic induction that are matched in the top, form synonyms pole and attract each other, produce adhesive kinetic energy immediately, make movable contact 4 separate stationary contacts 5 circuit, the outage of starter electromagnetic mechanism, cut off main circuit, water pumper stops pumping, so taking turns pump process and finish of water tower at this point.
When the water tower water supply volume is exported routinely, water level descends gradually, float 7 breaks away from the water surface, produce own wt, because of himself gravity lighter, attract the magnetic force of iron plate 3 less than permanent magnetism 2, still attracted, to play the effect intermittently that pauses, when water level 10 drops to lowest water level by the magnetic force of permanent magnet 2 with iron plate 3, the a chain of float 9 that the float 7 that is attracted by permanent magnet 2 and iron plate 3 is kept afloat by a chain of line 8 tractions is from going out the water surface, form the gravity that is fixed with straight down, then float 7 and a chain of float 9 gravity stack, greater than the attraction of permanent magnet 2 with iron plate 3, make iron plate 3 rapid and permanent magnet 2 disengagings, produce disengaging potential energy, make movable contact 4 and dead point closing of circuit, the energising of starter electromagnetic mechanism, main circuit contact, water pumper is again to water tower water-feeding, and under the water level buoyancy that rises, a chain of float 9 is kept afloat again, that goes round and begins again is circulated in said process, and nobody draws water automatically to realize water tower.
